About this tool
Not sure what shape your picture is? Drop it in and see its exact pixel size, simplified aspect ratio (such as 16:9 or 4:3), megapixels, file size and format. It handles many pictures at once, which is handy for checking whether a batch of images will fit a layout.
Everything is read locally in your browser.
Frequently asked questions
How do I find the aspect ratio of a picture?
Add the picture and read the Aspect ratio column.
Can I check many images?
Yes. Add several and export a CSV.
What if the ratio looks odd?
Pictures cropped to arbitrary sizes may not match a standard ratio. The tool then shows the decimal ratio.
Is Image Aspect Ratio Finder really free?
Yes. You can use Image Aspect Ratio Finder as often as you like with no sign-up, no watermark and no daily limit.
Are my images uploaded to a server?
No. Image Aspect Ratio Finder runs entirely in your web browser, so your files stay on your own device and are never sent to DEWANARO or anyone else.
